Facial palsy, clinically, includes peripheral facial palsy and central facial palsy. The common disease causing peripheral facial palsy is idiopathic facial nerve palsy. Patients usually present with loss of frontal lines and shallow nasolabial folds on the side of the lesion. There may also be incomplete eyelid closure on the side of the lesion, and the white tympanic membrane may be exposed when the eyes are closed, which can easily cause conjunctivitis. Therefore, eye shields should be worn when there is peripheral facial palsy, and eye drops can be ordered if necessary to prevent conjunctivitis. In case of central facial palsy, the common primary disease in clinical practice is cerebrovascular disease. Patients may also have limb sensory impairment or motor dysfunction. If the patient has limb motor dysfunction, he or she may be bedridden for a long time, which may cause deep vein thrombosis in the lower extremities. Pulmonary embolism may also be induced, leading to death, as well as possible decubitus infection.
